This is a long exposure shot made by combining the 275 individual 360° photos taken to make this timelapse video. It's only 90 minutes worth of shots, but the star trails are quite visible - and so is the gorgeous northern light show we got last night.

The star trails don't look quite straight, despite the camera being absolutely still the whole time. Unfortunately, the stitching process tends to shift the images ever so slightly at random, so the photos aren't perfectly aligned in pitch and yaw from one to the next. Shame...
